Terylene:
Preparation: terylene is prepared by a polyconensation reaction between a dicarboxylic acid and a idol.
Properties: a fully aliphatic polyester are not of much industrial importance because of their low melting points (50_80 degree c) introducing aromatic rings into the polyester chain a remarkable rise in the melting point of polyesters is produced due to resistant to heat and moisture and unattached by many chemicals.
(1) It has good mechanical strength up to 175degree c.
(2) Fibbers of Terylene have wrinkle resistance and high stretch resistance.
USES OF TERYLENE:
(1) Extensively used to make textile fibres.
(2) Used in the making of films which are used in the manufacture of magnetic recording tapes aluminised sheets for certain applications?
